Abstract Title: * A study of variability of KIC 9204718 observed in the Kepler field Institution: * IANAO Authors: * C.Ulusoy, I.Stateva, I.Kh.Iliev, B.Ulaş, M.Napetova Preferred format: * poster presentation Abstract Text: * We study the variability of the Am star HD 176843 by using Kepler photometry and ground-based high resolution spectrophotometry. From Kepler photometry the pulsational behavior of the star is studied obtaining two peaks of frequencies. HD 176843 is labeled as an Am stars and shows delta Scuti type pulsations. The star is thought to be a member of a binary system, too . Despite of some radial velocity variations there are not any sighs of binarity seen in the spectral line profiles.
